The company adopts the mandrel to push the seamless elbow pipe fittings, which can be produced in batches. In the push process can be pushed according to customer requirements of the wall thickness and material needs. The following is a brief introduction to the process parameters of seamless elbow pipe fittings pushed by mandrel:
Influence of mandrel head material and shape on push elbow geometry is an important technological parameter, which is directly controlled by design and manufacture.
Mandrel head material is generally 301.2520.18-8 and other materials, high temperature strength and wear resistance gradually increased, the price is correspondingly higher, if it is mass production, you can choose the above 304 is commonly used material, low price, quality assurance. Seamless elbow pipe fittings can be mass produced in the process of pushing. Mandrel heads are divided into single curvature according to radius of curvature. There are three kinds of double curvature and multiple curvature. Single curvature, double curvature, multi curvature mandrel, the thrust gradually decreased, the production cost gradually increased.
After customer order seamless elbow pipe fittings of time, will adopt double curvature mandrel, according to the cross section shape is divided into circular cross section and elliptical cross section two, circular cross section to make simple, low cost, elbow push system ovality and reduction ratio is too large, oval cross section production complex, high cost, but push the elbow of ellipse section and reduction ratio is small, the test select the elliptical cross-section mandrel. According to whether there is a corrective mandrel or not. The production of corrected mandrel is complex, high cost, long use time, the production of uncorrected mandrel is simple, low cost, but the front wear block, after the production of seamless elbow fittings over the New Year, our company has many years of production experience.
